MRAS identification of permanent magnet synchronous motor parameters

摘要

This article deals with the identification of synchronous motor parameters with permanent magnets using the model-reference adaptive system (MRAS). This method can effectively identify two parameters. These parameters are the stator resistance and the BEMF, under certain conditions as well as the direct inductance. MRAS method is based on two different models. One of these is in our case a real motor and the other is a simulated model based on the identified parameter. This identification was verified in simulations and then applied to a real motor.
